Definitions

  • This invention relates to combustion units and, in particular, to pulsating combustion units.
  • One type of prior art unit includes space-apart plates.
  • the unit typically includes a restriction downstream of the intake end.
  • the plates are spaced-apart closer together from the restriction to the exhaust end of the unit.
  • a high heat transfer coefficient is realized from the pressure gain environment as the gases move through the narrowed channel and are compressed.
  • the unit could be upscale do a larger output by extending the length or by placing multiple units side by side. However, this may not be feasible due to space limitations.
  • a pulsating combustion unit with an elongate combustion chamber having an interior cross-section, an intake end, an exhaust end and sides which are parallel from the intake end to the exhaust end.
  • intake means adjacent to the intake end and an exhaust outlet adjacent to the exhaust end.
  • the combustion chamber has a generally equal cross-section between the intake end and the exhaust end thereof.
  • the combustion chamber has a front plate, a rear plate and side plates, the front and rear plates being parallel and the side plates being parallel.
  • the cross-section is then rectangular.
  • the plates of the intake means are parallel to each other and parallel to the front plate and the back plate and are closer together than the front plate and the back plate.
  • Fig. 1 is an isometric view of a pulsating combustion unit showing the exhaust end thereof;
  • Fig. 2 is an isometric view thereof showing the intake end thereof;
  • Fig. 4 is an enlarged, isometric view of the pulsating combustion unit of Fig. 2 showing the intake spray bar thereof and being partly broken away to show the exhaust opening thereof;
  • Fig. 5 is a side elevation thereof, partly broken away;
  • Fig. 6 is a exploded isometric view thereof
  • Fig. 7 is a top plan view of the intake bulkhead thereof
  • Fig. 9 is an isometric view of a variation thereof having a substantially greater width than the embodiment of Fig. 4 - 8, one of the ends thereof being removed.
  • a pulsating combustion unit 10 according to an embodiment of the invention.
  • the unit includes a combustion chamber 12, an intake portion 14 and an exhaust portion 16. These may be compared with a prior art unit as shown in Fig. 3.
  • the unit includes a body 20 which is relatively wide adjacent to the intake portion 24 but which narrows significantly at restriction 25 towards exhaust opening 26. As explained above, this restriction in the interior cross-section significantly reduces the throughput of hot gases and accordingly the thermal output of the unit.
  • combustion unit 10 has a cross-section which is constant from the intake portion 14 to the exhaust portion 16.
  • the combustion chamber 20 has a front plate 30, a rear plate 32, which is parallel to the front plate, and side plates 34 and 36, which are parallel to each other and perpendicular to the front plate and rear plate.
  • the terms "front”, “rear” and “side” are somewhat arbitrary and are used primarily for clarity of the explanation of the unit. It may be appreciated therefore that the interior of the combustion chamber is rectangular in shape and has a constant cross-section between intake portion 14 and exhaust portion 16. However it should be understood that the cross-section does not have to be completely constant, it may taper slightly for example. However it does not have the marked restriction 25 found in the prior art of Fig. 3.
  • Igniter 100 is shown in Fig. 5 by way of example. It can be for example a spark plug. Alternatively the mixture can be ignited simply by a spark or a small flame placed adjacent to the spray bar.
  • Fig. 9 shows a combustion unit 1000 which is similar to unit 10 above but represents the equivalent of a plurality of such units placed side to side.
  • the unit is considerably wider between ends 102 and 104 thereof compared to unit 10. Otherwise the structure is similar.
  • the ends are closed with plates, but the plate at end 104 is removed for illustrative purposes.

Abstract

L'invention concerne une unité de combustion pulsatoire comprenant une chambre de combustion de forme allongée possédant une section transversale intérieure, une extrémité d'admission et une extrémité d'évacuation et des côtés parallèles allant de l'extrémité d'admission à l'extrémité d'évacuation. La chambre de combustion possède, de préférence, une section transversale généralement égale entre l'extrémité d'admission et l'extrémité d'évacuation. La chambre de combustion peut éventuellement comporter une cloison d'admission à proximité de l'extrémité d'admission. La partie d'admission comprend une fente dans la cloison et peut aussi éventuellement comprendre une paire de plaques espacées l'une par rapport à l'autre s'étendant vers l'extérieur à partir des fentes se trouvant dans la cloison. Ces plaques présentent, de préférence, entre elles un espace inférieur à celui qui les sépare de la chambre de combustion. La partie d'évacuation peut éventuellement comprendre une cloison d'évacuation dans laquelle est ménagée une ouverture.
